VFP won't run part of itself on each processor, but other things that can run in parallel (like the operating system, or other applications) won't get caught up waiting on VFP if VFP gets into a CPU-intensive operation.

Ed,

Do you know if there's any way to specify which processor should start a VFP session on an SMP box? I'd be a bit concerned trying to manage one, that two or more VFP instances might start up on the same CPU.
Regards. Al
